CAR-COUPLING. d

SPECIFICATION forming part of Letters Patent No. 402,391, dated April 30, 1889.

` Application iiled October 9 1888. Serial No. 287,661. (No model.)

To @ZZ whom it may concern.' Be it known that I, PHILIPl BOGLER, a citizen of the United States, residing in Stewart,

in the county of McLeod, in the State of Minv nesota, have invented a new and useful Car- Coupling, of which the following is a correct description.

The invention relates to that class of selfacting couplings in which the en gagingparts are alike upon each end' of the car; and the invention consists incertain improvements in the details of construction, which will be hereinafter particularly described and distinctly vertical section on the line w w in Fig. 1,*

looking in the direction of the arrow in that same by its flanges b2 b2, aretaining-plate, B,

of the rectangular form, most clearly represented in Fig. 6. Besides the perforated holding-flanges b2 the plate B is provided with side perforations to receive bolts b, in any desired number, by which it is additionally secured to the center sills; and it has in its transverse inner portion a central perforation, b', to receive the rearwardly-extending guide-bar or spring-carrying spindle c of the movable pivot-block C. i

As best seen in Fig. 3, the pivot-block C has at its outer or front extremitylateral jaws c' c', to receive the inner or rear extremity of the coupling and draw bar D; and, as seen in Figs. 2 and 5, it is supported upon a plate, E, which extends across and is rigidly secured to the bottom surface of the center sills, A2 A2. f

To the inner extremityof the 'pivot-block and this is in turn encircled by a spring, S,

each of the two springs bearing by Aitsends against the holding-plate C' of the pivot-block, and against the rear transverseportion ofthe retaining-plate B. y 4j y t At a point near its rear extremity the coup` ling and draw bar D is connected by a pivotpin, d, to the jaws c' c of the pivot-block, and this extremity of such bar is curved above and below in a vertical plane to permit its free movement upon its pivots.

At a short distance in advance of the pivotblock the coupling and draw bar D is connected by a spiral spring, d( to theupper securing plate, E', and by a corresponding spring, d2, it is connected to the securing and supporting plate E, the two springs operating in conjunction with the pivot-pin to maintain the bar normally in a horizontal plane. At its outer extremity the bar D is provided with a broad arrow-head, D', having upper barb, d3, and lower barb, d4, with corresponding upper and lower recesses, d5 and d, and having by preference vertical sides, as shown.

To any suitable loop or lug, Z, upon the side of the arrow-head D' is attached one end of a lifting or uncoupling chain, Z', the opposite end of such chain being connected to a lever, L, which is secured by a stout pivot-pin, P, to the body of the car, or, if it be a platform or hat car, to a suitable standard thereon. At its opposite extremity the lever L isprovided with an upperl operating-rod, R, for uncoupling from the roof of the car, and with a lower rod, R', for uncoupling from the ground, alongside the car. A stop, a, may be provided upon a fixed portion of the car to limit the downward movement of the inner end of the lever L and its connections.

IOO

In the modification represented in Fig. 8 the lever L receives a pivot-pin, p', and the lower operating-rod, R', is attached by a pivotpin,p10, to the body of the car. The heads D being exactly in line, the attachment of the lifting-chain at the side of each head permits it to pass over or under the coincident head without being obstructed by contact with such lifting-chain,as could not be done if the lifting-chain were conneced to the top of the draw-bar, either upon or at a point closely in rear of the arrow-head. There is thus very small space between two connected cars.

It will be seen from the foregoing description and from the drawings that the propulvsive strain is exerted primarily directly upon the barbs or hooks of the coupling and drawing bar D, and through such bar successively upon the pin d of the pivot-block, the holding-lugs or plate C of such block, and the upper and lower securing and supporting plates, E and E, upon the center sills of the bed-frame, the coupling-block being free to move outwardly and inwardly within suitable limits, and the anges or lugs c2 and c3 being engaged with or disengaged from the transverse plates E and E, according as the j drawing-bar is moved outwardly from or inwardly toward the center of its car.

The springs s and S, the one within the other, at the rear of the pivot-block, will operate inthe ordinary manner to break the jar resulting from bringing two cars together; but as a further means for relieving the shock and strain of concussionI provide at the ends of the side sills, aA12 A, sockets a5 w" to receive buffersprings a, which bear at one end against the bottom of the socket and at the opposite end against the inner extremity of buer-spring head a7. As a substitute for these buer-springs at the ends of the side sills, or as auxiliary thereto, similar sockets and buffer-springs may be applied directly to the exterior surface of the end sills at points coincident with the intermediate sills of the bed-iframe.

It being understood that the above-described mechanism is provided at each end of each car, it will be manifest that in bringing two cars together one of the two coincident arrow-heads will rise upon, pass along,

and fall behind the other, and that it is wholly immaterial which of the two may be uppermost, since the result is, unavoidably, to interlock the barbs of the two arrow-heads as one car is moved away from the other, and since the operation of uncoupling may be effected' with equal facility from either end of each and every car.

It will be obvious that it is immaterial whether the holding flanges or lugs c2 and c3 be formed upon a separate plate, as C', for subsequent attachment to tho pivot-block, as in Fig. 1, or Whether the plate C and its lugs be formed integrally with such pivot-block, as in Fig. 9.

Having described my invention, I claiml. The combination, with the bed-frame of the car, having the transverse plates E and E, of the pivot-block C, provided with horizontal flanges c2 and c3, loosely engaging the plates E and E and carrying the pivoted draw-bar D, substantially as specified.

2. The combination, with the bed-frame of thecar, having the transverse platesE and E, of the pivot-block C, engaging such transverse plates and provided with the vertical jaws c c', carrying the spring-supported dran bar D, and provided also with the rearwardly-extending springcarrying spindle c, substantially as shown and described.

3. The combination, with the bed-frame A', of the pivot-block C, having the top and bottom horizontal flanges, c2 and c3, and the vertical jaws c c', and the draw-bar D, pivoted in the jaws c', and provided with top and bottom sustaining-springs, d and cl2, substantially as specified.

4. The combination, withvthe pivot-block C, having engaging-Hangers, vertical jaws, and rearwardly-extending spindle, of the drawbar D, pivoted in the Vertical jaws of the block C, provided with top and bottom springs and with arrow-head, and havingliftingchain Z', attached to the side of such arrow-head, substantially in the manner and for the purposes set forth.

PHILIP BOGLER.
